Scooby and Shaggy are filming an episode of their cartoon as they are running from "The Crabby Creature of Creepy Crag." After Scooby and Shaggy fall on the ground after going through a catapult, they start getting tired of doing the same routine, and decide to become real movie stars. They show the president of a network, C.J., a pilot film called ''How the West Was Won (TV series)'', where Sheriff Scooby and Deputy Shaggy undergo the ornery Jesse Rotten. C.J. believes the film is a joke, and throws Shaggy and Scooby out, laughing. After the gang finds out Scooby is leaving the show, they protest while Shaggy tells how Scooby will become famous.
